Native Rendering Plugin Support in VR

Hi,

Unity native plugin(https://bitbucket.org/Unity-Technologies/graphicsdemos) was not updating any content in android platform. This can be solved with adding an DrawTexture() call in OnGUI(). But, GUI display is not working when native VR is supported.
So, How to bring up native rendering example when native VR support is enabled?(Example: Daydream with unity v5.6beta).

Thanks,
Pradeep
